您好，我需要通过api网关从dynamodb获取一个项目，我将资源配置如下：

我配置集成方法，如下图所示：

映射模板如下所示：

但是当我测试apigateway时，会出现这个错误

Execution failed due to configuration error:
No match for output mapping and no default output mapping configured.
Endpoint Response Status Code: 200
Gateway response type: API_CONFIGURATION_ERROR with status code: 500

我遵循这两个教程，在dynamoDB表上执行了get

我的表有主键名“pk”。教程：&

如果我像你一样写我的迪纳摩请求体，它不会得到任何记录

但是如果我像这样提出我的要求

{
    "TableName": "apiG",
    "PrimaryKey": "pk",
    "KeyConditionExpression": "pk = :v1",
    "ExpressionAttributeValues": {
        ":v1": {
            "S": "key1"
        }
    }
}

我从dynamoDB得到了期望的响应

您的错误看起来好像在集成响应和方法响应中有一些混淆。以最简单的形式，将方法响应保留为默认值，即“HTTP状态：200个模型：application/json=>为空”，并在API网关控制台为您创建集成响应时保留集成响应

这将确保在不修改浏览器/输出的情况下发送DynamoDB输出

我在集成响应中使用以下映射模板转换了dynamo输出

它产生了如下输出

{
  "content": [
    {
      "key": "key1",
      "value": "val1"
    }
  ]
}

另外，我有一个名为“apiG”的dynamo表，上面有primaryKey“pk”，并遵循我实验中导出的招摇。希望能有帮助
